No options sticker in the trunk. Any ideas how to understand which disks/pads for brakes?

Hi,

I have car, bought in 2019 from Finland dealer. Neither trunk compartment or user manual contain options sticker. Engine code is given on passenger's door sticker. But no usual option codes.
Need that information to order correct front brake pads/disks. Mine is 2018 FR 1.5TSI.
Is there any good way to figure out which brake system car is running? Take it apart and measure disks/pads (currently don't have this opportunity, will have in a week or so? Call dealer?

Also, curious, if I am running smaller brake set in the front (256x22), wonder if upgrade to 276x24 is possible. Probably need calipers/disks/pads/master cylinder. Wonder how brake balance is regulated on these cars. Is it still oldschool in the master cylinder or ABS unit somehow is taking that into account.

A bit confused here .

Yes, the coding of the braking system is noted in the ABS.

VIN?

Managed somehow to measure the disks through the wheel spoke gaps. It seems I have 276x24 already. Which is logical, because 1.5tsi seems to be most powerful version. Probably brake disks looked so small, because of relatively large R17 rims.
